Question

White-box software testing techniques. Perform basis path testing to the average function.

**A.)** Based on the basis path testing, how many
test cases should be applied to the average function? Why?

**B.)** What are these basis paths? Give a sample
test input for each test case.

Answer #1

Generate test cases for the following code by using Basic Path
Testing.
void sort(int a[ ],int N)
{ int i,j,p,t;
for(i=0;i<N-1;i++)
{ p=i;
for(j=i+1;j<N;j++)
if(a[j]>a[p])
p=j;
if(p!=i)
{ t=a[p]; a[p]=a[i]; a[i]=t; }
}
}
a) Draw CFG.
b) How many basic paths
for the CFG?
c) List the basic
paths.
d) Generate test cases
from it.

Coca-cola is testing a new processing line for filling 16-oz.
bottles. They perform a test run in which 100 cases, each
containing 24 bottles, are completed. From this test-run they
randomly select 6 cases and take measurements on 5 randomly
selected bottles from each case. Results for each of the six cases
are shown in the table below. Estimate the average number of ounces
per bottle and provide an appropriate error bound for your
estimate.

(Hypothesis Testing Questions) You perform the Hypothesis test,
and you find the following information. What would be your
conclusion and why? A coffee shop relocates to Italy and wants to
make sure that all lattes are consistent. They believe that each
latte has an average of 4 oz of espresso. If this is not the case,
they must increase or decrease the amount. A random sample of 25
lattes shows a mean of 4.6 oz of espresso and a standard...

AHW2) Hello I have an agile software development methodology
that is proposed by the combining the two other agile development
methodologies, my question is how can I draw its process model that
describe it entirely(as drawing graphs). The description of the new
proposed methodology is given below:
1. The new Agile methodology is "Feature and Test Driven
Development".
2. Feature Driven Development (FDD) is an iterative and
incremental Agile methods
for developing software. This is client centric pragmatic Software
process....

(a) Write an algorithm (use pseudo-code) to determine whether a
function
f ∶ Z100 → Z100 is surjective. That is, supply a “Method” to go
with
Input: A function (array) f with f(i) ∈ Z100 for i = 0, 1, . . . ,
99.
Output: Boolean B. B=‘true’ if f is surjective, ‘false’
otherwise.
Try to make your algorithm as efficient as possible.
Do NOT include an implementation of your algorithm in a programming
language.
(b) How many comparisons...

BACKGROUND: According to the Educational Testing Service (ETS),
the national average on the Graduate Record Examinations (GRE), a
standardized test that is an admissions requirement for most
graduate schools in the United States, is 302.60 (with the verbal
and quantitative subsections combined). Unfortunately, ETS does not
provide a standard deviation for total GRE score (only standard
deviations for the two subsections), so let’s just use a standard
deviation of 12.
PROBLEM (FICTIONAL): ETS has received number complaints from
universities that...

Question 1
The Inland Revenue Board says that the average income in Taiping
is RM15000. A sample of 45 people found that their mean income to
be RM14300 with a standard deviation of RM2000. (a) Use a 5%
significance level to check the claim. [18 marks]
(b) Test the effect of using a 1% significance level. [8
marks]
(c) If there is a difference in the two test results, explain
the reason for the difference....

In this discussion, you will apply the statistical concepts and
techniques covered in this week's reading about hypothesis testing
for the difference between two population proportions. In the
previous week’s discussion, you studied a manufacturing process at
a factory that produces ball bearings for automotive manufacturers.
The factory wanted to estimate the average diameter of a particular
type of ball bearing to ensure that it was being manufactured to
the factory’s specifications.
Recently, the factory began a new production line...
